One of the interesting additions with BC is the ability to choose a particular faction which to build rep with - at the expense of another important faction. Similar to the Steamwheedle vs. Bloodsail or Mangrum vs. Gelkis factions, building rep with the Scryers actually lowers your Aldor faction and vice-versa so choose wisely.

Upon your first visit to Shattrath, you are posed with a quest from Khadgar to take a tour of the city. When you return to him, he asks you to pledge your allegiance to either the Aldor or the Scryers. Completing this part of the quest will give you 3500 rep with the chosen faction and will cause you to lose 3750 rep with the other. This will effectively make you Friendly with one and Hostile with the other.

At some point in time, you may decide to change your allegiance to the opposite faction. This can be done, but the method of switching can be arduous. You not only will not have the advantage of the initial boost from Khadgar’s quest, you will have to do an RRQ many times to get to Friendly before you can start proceeding as normal with the above mentioned quests. Each RRQ at this level is worth 250 rep for the appropriate faction and will cause you to lose 275 rep with the opposite faction.

Switching from Aldor to Scryer faction:Gather as many Dampscale Basilisk Eyes as you can and start turning them in to Arcanist Adyria in Lower City. At 8 eyes per turn-in, you can expect to kill a lot of basilisks. (It will take 15 turn-ins, or 120 eyes, if you completed the initial quest from Khadgar and nothing else.)You can find more information on the quests at:http://wow.allakhazam.com/db/quest.html?wquest=10024

Switching from Scryer to Aldor faction:Gather as many Dreadfang Venom Sacs as you can and start turning them in to Sha’nir in Lower City.
